The Design Brief
Standard vacuum cleaner bags clog with
dust reducing efficiency

• In 1978 James Dyson noticed that the bags on
  standard vacuum cleaners quickly clog with dust
  reducing suction and efficiency.
• He invented a bagless cleaner using cyclone
  technology to solve the problem.

James Dyson replaced the bag with a cyclone to
solve the problem

Sketching

• Sketching is a quick and cheap way
• of working through ideas and
• communicating those ideas to the
• design team.
• Design engineers create many
• sketches in a short space of time.

Test Modelling

• Dyson design engineers move as
• quickly as they can from the initial
• brief to working in 3D. They make
• prototypes out of many different
• materials.
• They often work in cardboard as this
• allows them to make 3D models very
• quickly, cheaply and easily.

Computer Aided Design

• CAD is a useful tool at this stage as
• it means you can begin to construct
• an accurate model with precise data,
• which can then be used for other
• processes such as rapid prototyping
• and, later on, tooling.

6
Rapid Prototyping

• Dyson uses a rapid prototyping
• process called fuse deposition
• modelling (FDM).
• It means that accurate plastic
• components can be made in a very
• short period of time overnight in
• most cases.

Colour

• Dyson vacuum cleaners come in a
• range of different colours depending
• on the different models. However,
• different coloured plastics have
• different properties and react in
• different ways.
• This means that Design engineers
• have to decide on colours before the
• prototypes are tested.

8
Testing

• Rigs are developed to test every
• aspect of the design e.g. the wheels
• the catches the hinges and of course
• the cyclone to make sure that the
• product will be tough enough to
• withstand daily use.

9
Tooling

• When the design engineers have
• tested every component and are
• happy with their working prototypes,
• then the CAD data is sent to the
• toolmakers, in order to make the
• injection moulding tools. The tool for
• each component is made from a
• huge block of steel, and costs
• thousands of pounds to make.

10
Quality Control

• The first parts back from the
• Toolmakers are inspected very
• carefully to check their quality. If any
• of the imperfections are obvious, then
• the tool will have to be adjusted.

11
Assembly

• Right at the beginning of the design
• process, at the cardboard modelling
• stage, design engineers were
• thinking about how their product
• would finally be assembled. The
• less parts a product has, and the
• easier they fit together, the quicker
• and more efficient the assembly
• process.
